Well another weekend and still no progress on speed of JIT, .
So started porting to Notaz's DYNAREC, just working on making it stable.
Fingers crossed as this is last attempt. Fedup of JIT, stuff now. Been on it since Feb this year.

I have added overclock options to PSPUAE, so you can overclock PSP if you have plugin or using ARK CFW.

Current state of pspuaev2,it now has Normal UAE CPU, FAMCE/C, JIT and DYNAREC all controllable via makefile flags.Read More

Well spent most of latter end of week on JIT.
I now realise although its working. Its slow due to me working around the x86 code.
So I am now altering code based on allegrex mips assumptions instead of x86.

Started with unified registers. That instantly showed CPU usage drop, so will continue working on it tonight and the weekend, hopefully I can get the speed out of it I have been after.

Well spent all weekend, tweaking FAME/C and JIT.

Result FAME is working as it should and perfect.
JIT is now fully working (bare in mind this is a full industrial style JIT, not a DYNAREC). Just needs tweaking to nail all speed issues (if I ever can, on this 333MHz).
However important thing is, it works fine without crashing regardless of JIT options set (used to crash randomly depending on options).

All Yesterday, spent time profiling paula on ME. Reduced alot of wasted time via irq polls etc etc.Read More

Well I have profiled every part of source and nailed all stuff hogging CPU. I have literally squeezed as much out of it as I can with out breaking stuff.
To be honest, you will never get 100% speed on 333MHz. I realise now, my PSP was clocking at 444MHz when I saw big speed increase. .
I will keep at it, worked on FAME/C last couple of days. Its running ok, just not hooked into full E-UAE core framework yet.Read More
